This Sigma 1 Greater Noida Map guide explains the plots, roads and facilities in detail. Sigma 1 is also marked on the Authority’s plan as Sector 42, which is why buyers search for both names. It is a large, planned plotted sector with just two plot sizes, wide 80 m and 60 m boundary roads, a big integrated school complex and two master-plan commercial belts.
This guide reads the official Sigma 1 layout plan and its area statement for you. The full interactive version is on our Sigma 1 map page.

Sigma 1 Map Data: Plots and Area Statement
Sigma 1 has only two plot sizes, which makes it easy to understand:
| Plot area | Dimensions | Approx. size | Plots |
|---|---|---|---|
| 500 sq m | 31.25 m × 16 m | 5,382 sq ft | 297 |
| 300 sq m | 24 m × 12.5 m | 3,229 sq ft | 748 |
That is 1,045 plots in total. The 500 sq m plots (salmon on the plan) sit in Block A in the north, while the 300 sq m plots (blue) fill Block B in the south. The area statement shows how the net sector area of about 85.9 hectares is used:
| Land use | Area | Share |
|---|---|---|
| Residential development | 41.27 ha | 48.0% |
| Roads | 23.05 ha | 26.8% |
| Green areas (including parks) | 15.03 ha | 17.5% |
| Facilities | 6.60 ha | 7.7% |
Outside the net area, the plan also sets aside about 7 ha for master-plan commercial belts, 2.9 ha for village abadi and 4.6 ha for the master-plan green belt. The planned population is about 11,575 people, with about 55.7% of the area saleable.

- Block A (north): 500 sq m plots on 12 m and 9 m roads, with a central park and a facility strip.
- Block B (south): 300 sq m plots in long rows between 12 m and 18 m roads, with several parks and a community hall site.
- Integrated school complex: a large school site in the north-west corner, a major plus for families.
